IUFFLER FOR MONOXIDE GAS ELIIIKATION Filed Nov. 28., 1940 Patented Nov. 18, 1941 UNITED. STATES PATENT oEE cE MUFFLER FOR "GAS ELIMINA- Julius o. Kittell; sri, San Pedro, Calif.

Application November 28, 1940, Serial No. 3671485 1 Claim. (01. 181-43) My invention relatesto mufllers and more particularly to such devices which are especially adapted for collecting and for allowing the gases flowing therethrough to be mixed with incoming air and then allowing said mixed gases to gradually expand therein and thereby eliminating to a great extent the carbon monoxide gases and the smoke from said gases which are exhausted from the internal combustion engines.

Manifestly an object of my invention is to provide a suitable muilier means which is con-.

nected to the exhaust pipe of the internal com- 'bustion engine, said muilier means having suitair to enter therein and for mixing with said a exhaust gases within said muiiler, also having means for exhausting said mixed gases from said mui'iler silently and entirely and thereby eliminating the carbon deposits and the monoxide gases which are produced by the unburned hydrocarbons used in the operation of the internal combustion engines.

Therefore an object oi my invention is to pro vide a suitably constructed mumer means having a conduit member for conducting the engine exhaust fluids into and through said muilier means. said muiiier means having a suitably constructed Venturi tube means forming an orifice for drawing in and for diffusing the incoming air fluid with the volume of the incoming exhaust gases, also having an air volume controller and air diffuser member associated therewith for deflecting the air stream into said Venturi tube means for increasing its mixing capacity and when so mixed with a comparatively cold air thus causing a reduction of the gas pressure and in addition having a high velocity gas conduit member passing through said muiiler means for drawing and for exhausting the mixed gases therefrom and thereby reducing considerably the carbon monoxide gases and the carbon deposits in said mumer ;means.

Other object of my invention is to provide said muifler means with an adjustable air inlet plate member which is provided with a plurality of adjustable baflle plate means for increasing or decreasing the volume 01' air passing into said mui'iier means and in addition which is adapted for deflecting said air at diversified angles and thereby increasing or decreasing the said muiller means with a suitable collector member having an intake and an exhaust passage, said intake passage having a suitable Venturi tube means associated therewith for drawing the cold air into said collector memberand {or mixing and expanding the passing gases therein, thereby producing a negative pressure in said collector member and for reducing the carbon monoxide contents in said mixed gases while passing through said collector member and at the same time silencing the gas discharge passing through the discharge passage of said muiiier means.

Other and further objects and advantages of my invention as will hereinafter more fully appear, I attain by the construction herein shown on the drawing and described in the specification forming a part of my application.

Reference is .had to the accompanying drawing in which the similar reference characters donote the similar parts.

In the drawing:

Fig. 5 is the vertical sectional view of the muiller showing the elevational view of the exhaust passage and in relation to the high velocity invention is provide tube, taken on the line 5-4 of the Fig. 1.

Describing my invention more in detail said invention comprises a 'muiiler generally designated by numeral 2, which consists ot a tubular 1 housing member 4 having an intake end I and the discharge end member 8.

Said intake end i is provided with a suitable air controller plate II which is equipped with a suitable flange l2 for connecting same thereto as shown, having its center provided with the gas intake pipe and also having its mid-section l6 provided with a plurality of apertures 18, each of which is equipped with an individual deflecting plate member 28.

The intake pipe 14 extends inwardly and into I said housing member 4, having its end 22 in line and in position with the edge 24 of the Venturi tube member 26, it being made an integral part of the plate member 28 of which its edge is provided with a suitable flange 36 for connecting and for mounting same in place and within said tending approximately between the intake end 6 and the discharge end 6, a suitable high velocity tube 36 is positioned which is held in place by nected to said housing member 4 as shown, having theintake end 48 of said high velocity'tube 36 placed partially within the end 22 of said intake pipe l4, while its discharge-end 42 is positioned slightIyBo'the rear of the orifice 44 formed at the exhaust pipe 46- for forming a gas convection while the apparatus is in operation.

For holding said exhaust pipe 46 in place and position, it is made an integral part of the end plate member 48, having a suitable flangeifl for connecting same to the discharge end member 8.

In operation, the exhaust gases passing from the internal combustion engine enter the mufller 2 and the housing member 4 through the gas intake pipe l4 and continuing in its passage through the high velocity tube 36 and discharging a'portion of said gases into the exhaust pipe 46.

At the orifice 34 said passing gases form a partial vaccum which draw the air passing through said apertures l8 and due to the angular position of said deflecting plate members 28 said air changes its course of travel and forms a spiral whirl within said housing member 4 which greatly increases its mixing effectiveness with the incoming exhaust gases, further, due to an extrememeans of spider members 38 and which are contube 36 at the orifice 44 of the exhaust pipe 46 and thereby discharging the exhaust gases through said apparatus greatly minimized in percentage and the contents of said carbon monoxide gases and also reducing considerably the carbon deposits in said housing member 4.

In practice it has been found that the most satisfactory proportions of the exhaust gases and the air at the restricted orifice 34 is at 50% per volume taking into consideration the internal diameter of the high velocity tube 36 which draws only 5% of the discharged gas volume passing through the intake pipe l4- from the internal combustion engine, and that in the Diesel fuel engines, said proportions may be adjusted in accordance with the efliciency of the fuel jets and by increasing the diametral: size of the Venturl tube member 26 including the area of the apertures l8.

While I have thus described my invention with great particularity it will be clear that the same may be modified throughout a wide range.

I accordingly do not propose to be limited to the' exact details of construction herein shown on the drawing and described in the specification, but reserve the right in practice to make the necessary changes and modifications therein which may come within the scope of the ap-- v pended claim.

I claim as my invention:

A muflier of the class described adapted for use in connection with internal combustion engines, comprising a housing having a gas inlet tube and a discharge pipe, an air controlling plate positioned at the inlet end of said housing having said gas inlet tube passing therethrough, a gas inlet tube end disposed in said housing, a plurality of apertures disposed in said air controlling plate for permitting said air to enter into said housing, a baille plate connected to each of said apertures for deflecting said passing air and for whirling said air while passing through said housing, a Yenturi tube means mounted within said housing having its-orifice at the end of said gas inlet tube for drawing and for mixing said gas and said air passing therethrough, and a high velocity tube means centrally positioned in said. housing having its inlet end positioned in the center of said gas inlet tube end and the exhaust end positioned at said discharge pipe for creating a gas convection and thereby discharging said mixed gases from said housing, substantially as described.
